Perpetuity01:18

Perpetuity

A perpetuity is a financial instrument that provides indefinite, regular payments. Unlike fixed-term financial products, perpetuities continue indefinitely, which makes them unique in the realm of investment and valuation. A typical example is preferred stock, which  are shares of a company that guarantee fixed annual dividends. Investors receive a steady income as long as the company continues to operate and pay dividends.
There are two types of perpetuities: simple and growing. Simple...

Imaging Mycobacterium tuberculosis in Mice with Reporter Enzyme Fluorescence10:06

Imaging Mycobacterium tuberculosis in Mice with Reporter Enzyme Fluorescence

We describe the optical imaging of mice infected with Mycobacterium tuberculosis (M. tuberculosis) using reporter enzyme fluorescence (REF). This protocol facilitates the sensitive and specific detection of M. tuberculosis in pre-clinical animal models for pathogenesis, therapeutics and vaccine...

The MODS method for diagnosis of tuberculosis and multidrug resistant tuberculosis23:06

The MODS method for diagnosis of tuberculosis and multidrug resistant tuberculosis

The microscopic-observation drug-susceptibility (MODS) assay is a low-cost, low-tech tool for high-performance detection of tuberculosis (TB) and multidrug-resistant tuberculosis (MDRTB). This video describes the MODS liquid media culture...

An Experimental Model to Study Tuberculosis-Malaria Coinfection upon Natural Transmission of Mycobacterium tuberculosis and Plasmodium berghei09:02

An Experimental Model to Study Tuberculosis-Malaria Coinfection upon Natural Transmission of Mycobacterium tuberculosis and Plasmodium berghei

Tuberculosis and malaria are two of the most prevalent infections in humans and major causes of morbidity and mortality in impoverished populations in the tropics. We established an experimental model system to study outcome of malaria-tuberculosis coinfection in mice after challenge with both pathogens via their natural route of...

An In Vitro Caseum Binding Assay that Predicts Drug Penetration in Tuberculosis Lesions12:17

An In Vitro Caseum Binding Assay that Predicts Drug Penetration in Tuberculosis Lesions

Here we describe a rapid equilibrium dialysis (RED) method to measure drug binding to caseum from pulmonary tuberculosis lesions and cavities. The protocol is also used with a foamy macrophage-derived matrix that is an effective surrogate to...

COVID-19 / Coronavirus Outbreak: A Rapidly Deployable Medical Facility Optimized for Epidemics (Smart Pod)01:19

COVID-19 / Coronavirus Outbreak: A Rapidly Deployable Medical Facility Optimized for Epidemics (Smart Pod)

The Centers for Disease Control and Prevention (CDC) recommends that healthcare providers perform screening tests on patients with symptoms of COVID-19 in an isolated room to protect other patients from potential exposure to the virus. 
The Smart Pod, a rapidly deployable medical facility that was designed in the wake of the Ebola virus, can serve as a biocontainment unit for airborne pathogens. This emergency solution has been developed by Baylor College of Medicine as a nimble,...
